Between my 6 and 7 year old boys, and my 6 year old nephew, I’m surrounded by the Lego obsessed! And I have to admit, I have fun helping put together the sets myself… So when my nephew’s birthday came around I got inspired – and made the Building Blocks Crochet Backpack!
The Building Blocks Crochet Backpack is a simple pouch with a set of drawstrings that close up the top and double as the straps. I used Red Heart Super Saver to make sure it could stand up to a 6 year old boy – but any worsted or aran weight yarn should work just fine!
Building Blocks Crochet Backpack Pattern
- US – I, 5.5mm hook
- 390 yards total worsted weight yarn in 5 colors (Red Heart Super Saver in Cherry Red, Paddy Green, Royal, Lemon, and Black shown)
– Red, Green, Blue, and Yellow: 40 yds each
– Black: 230 yds
- 2 54″ long nylon type cords (can substitute crocheted icord if desired)
- Special Stitch: dc3tog – worked as a bobble stitch, with all sts worked into the same st, but with only 3 dcs instead of 5.
- Video Tutorials: bobble stitch, seamless join, BLO – back loop only, FSC – foundation single crochet, LTR – linked treble crochet
Make 25 Lego Blocks:
Yellow – 7
Red – 6
Green – 6
Blue – 6
Row 1: Ch 7, skip the ch closest to the hook and sc in each remaining ch. Turn. (6 sts)
Row 2: Ch 1, sc in the 1st st, dc3tog in the next st, sc in the next 2 sts, dc3tog in the next st, sc in the last st. Turn. (6 sts)
Row 3: Ch 1, sc in each st, turn. (6 sts)
Row 4 – 7: Repeat Rows 2 – 3 twice.
Row 8: Repeat Row 2.
Edging: Ch 1, sc in the first 5 sts of the previous row, 2 sc in the next st. Rotating to work down the left edge, work 7 sc into the side. Working along opposite side of the starting ch, work 2 sc in the first st, sc in the next 4 sts, then 2 sc in the last starting ch. Rotate again to work along right edge of block, work 8 sc into the side. (30 sts) Break yarn and seamless join to 2nd st of edging.
Joining the Blocks:
The blocks are joined in a 5×5 grid, using Black yarn, as shown below (Y for Yellow, R for Red, etc). Be sure that the blocks are all arranged the same way – with the Row 1 end next to a Row 1 end and Row 8 end next to a Row 8 end. Sc them together by holding the wrong sides together and crocheting through the inside loops of the sts – the back loop of the block facing you, and the front loop of the one facing away from you.

I found it easiest to work all of the 1st and 2nd column blocks together in one long row, and then add the blocks for column 3, and so on. Then I went back and stitched the ends, or horizontal rows together. This way there are only 8 links to crochet and 16 ends to deal with. This finished piece should measure approximately 11″ wide by 13″ high.
Back Side Instructions:
(If you prefer, sc sts can be substituted for LTR sts, just make the same size as the finished Lego piece.)
Row 1: Using Black Yarn, FSC 38, turn. (38 sts)
Row 2 – 16: Ch 3, work LTR in each st to end. Turn. (38 sts)
Row 17: Ch 2, work LDR (linked double crochet, same as LTR but with only one loop pulled up) in each st to end. (38 sts) Do not turn or break yarn.
Place the Lego piece on top of the Back Side piece, with Right Side of the Legos facing out and the active loop of the Back Side on the upper left (as shown above). Working through the BLO of the Lego blocks and both loops of the Back Side, sc evenly along the left edge of the bag, across the bottom of both pieces, and up the opposite edge, leaving the top of the bag open.
Work around the top of the bag as follows:
Round 1: Ch 1, sc in the BLO across the Lego side and in both loops of the Back Side. Join to the first sc of this round with a sl st. (76 sts)
Round 2: Ch 4, skip the 1st and 2nd sts. (Counts as 1 dc and 1 ch.) *Dc in the next st, ch 1, skip next st. Repeat from * to end. Break yarn and seamless join to the 3rd ch. (38 dc, 38 ch)
Add the Bottom Row:
With the Lego side facing you, rejoin the Black Yarn to the bottom right corner of the bag with a sl st. Ch 1, sc in the same st. Ch 2, sc in the next st. Sc in each st across the bottom of the bag until 1 st remains. Ch 2, sc in the last st of the bottom. Break yarn and weave in ends. (There are now “holes” in each bottom corner of the bag.)
Weave each cord through the ch 1 sps of Round 2 of the top as shown below, so that both ends of each cord come out on the same side, with one cord having both ends on the right, and the other having both ends on the left.
Thread both ends of each cord through the bottom corner hole on the same side of the bag, going front to back (in on the Lego side, out on the back side). Tie them in a knot so they won’t come back through the hole, and if using nylon/plastic cord use a lighter or match to melt the ends together (adults only please!). If using crochet or knitted icord, you may need to make two knots, or sew them in.
And that’s it! Pull the drawstrings a bit so the top closes, and the Lego Inspired Crochet Backpack is ready to wear!
I hope you enjoy making this crochet backpack – and I hope your Lego-loving littles enjoy wearing it! The linked trebles keep the back piece nice and solid, so little pieces don’t escape. Pair it with a new set of Lego blocks and you’ll be the favorite aunt/ grandma/ mom/ person for sure!
